\Ve do not describe in this specification the lever and means whereby all shoes of the machine are raised simultaneously, as such means form no part of our invention; but We may merely state that each shoe is adjusted in relation to the feed-run either to apply varying degrees of pressure or to elevate the shoes for transportation, and the tubular conveyers are held together during such movements by reason of their telescopic connection.

Our tubular conveyers are so arranged that the end of the tubular conveyer K extends sufficiently far into the tubular conveyer K, so as to absolutely prevent them being disconnected by any adjustment of the shoes in relation to the feed-r-un caused by such shoes traveling over the unevenness of the groundsurface. In order to attach the tubular conveyers, they must first be telescopically connected, and it is then merely necessary to insert the thimble of the lower tubular conveyer into the socket L and then insert the split pin over the hook. The top of the upper conveyer may then be connected to the pins attached to or forming part of the feed-run.

Should the lower tubular conveyer become broken or injured and it be desired to detach the lower tubular conveyer K, this may be readily and quickly done by simply withdrawing the split pin N, instead of as at present required by detaching the drag-bars and the pressure-rod and spring.

Although we describe in this specification the tubular conveyers as connected to a shoe such as described it will of course be understood that they might be used with any suitable runner or other device designed to open the ground and deposit the seed.

What we claim as our invention is-- 1. The combination with a seeding-machine having a seed-run and shoe, of a conveyer leading from said seed run to said shoe, said conveyer being formed of telescopic sections,

the detachable connection between the upper end of said conveyer and said run, and the positive connection between the lower end thereof and said shoe, said connection being freely detachable.

2. The combination withaseeding-machine having a seed-run and shoe, of a conveyer leading from said run to said shoe, said conat. In,a seeding-machine a shoe or runner suitably supported, a conveyer-socket secured between the sides of the shoe at the rear end thereof, a tubular conveyer extending upwardly from such socket and a hook at the bottom rear end of the tubular conveyer and a suitable pin or projection with which it is designed to engage as and for the purpose specified.

5. In a seeding-machine a shoe or runner suitably supported, a conveyer -socket secured between the sides of the shoe at the rear end thereof, a U-shaped extension to such socket and pin extending through such U -shaped extension and the tubular conveyer having a hook formed at its rear bottom end, and the coacting pin extending through the U-shaped rearward extension as and for the purpose specified.

(5. In a seeding-machine a shoe or runner suitably supported, a conveyer socket secured between the sides of the shoe at the rear end thereof, a U-shaped extension to such socket and pin extending through such U-shaped extension, the tubular conveyer, the thiinble forming the extension thereof provided with an exterior intermediate flange and having the end abutting an annular shoulder in the top of the socket against which the end of the thimble abuts, and a hook on the thiinble designed to grasp the pin extending through the U-shaped extension as and for the purpose specified.
